Eye health is set to become one of the great health concerns of the modern age and a major nutraceutical interest. Aging population, increasing exposure to screens, poor nutritional habits and dropping food quality are all affecting eye health globally with no prospect of trend-reversion.
Considering 80% of European 12 to 15-year-olds have their own (smart)phones, and American children aged 8 to 10 spend approximately 6 hours each day using multimedia devices, according to a study published in the journal New Media & Society in 2015,1 it’s no wonder supplementation interest in form of web searches has risen by 50% in the past five years, according to Google Trends.
Vision is one of the categories where the gap between demand and availability of innovative solutions is most surprising.
Though genetics may play an important role in vision impairment development, lifestyle has a major impact on our eyes’ health.
Environmental exposure, especially to UV and high energy blue light—the light emitted by our digital devices’ screens, and artificial indoor lightening—but also smoking, considerably impact our eyes health.
High-energy blue light radiates with the shortest wavelengths—thus having the highest energy. Daily screen exposure can cause eye strain and dry eyes in both adults and children, resulting in unnecessary eye exhaustion.
Increased and prolonged exposure to high-energy blue light could be associated to the recent rise of nearsightedness diagnoses in children, since the cornea is not fully developed before the age of 14. This is particularly worrying since most children own digital devices, and often use several at once.
Use of digital devices at night also disrupts individuals’ circadian rhythm, as high energy blue light impacts the body’s natural production of melatonin. Several studies demonstrated that over time, high energy blue light cumulative effects cause important damage to the macula, resulting in an increased risk of developing AMD.
